CLK_GET(9)							  Clock Framework							CLK_GET(9)

NAME
       clk_get - lookup and obtain a reference to a clock producer.

SYNOPSIS
       struct clk * clk_get(struct device * dev, const char * id);

ARGUMENTS
       dev
	   device for clock "consumer"

       id
	   clock consumer ID

DESCRIPTION
       Returns a struct clk corresponding to the clock producer, or valid IS_ERR condition containing errno. The implementation uses dev and id to
       determine the clock consumer, and thereby the clock producer. (IOW, id may be identical strings, but clk_get may return different clock
       producers depending on dev.)

       Drivers must assume that the clock source is not enabled.

       clk_get should not be called from within interrupt context.
